Since Philip was a stubbornly spendthrift fellow, that meant Marigny’s chief pursuit was the creative extraction of new revenues, through fresh taxes and the debasement of coinage. His public esteem suffered commensurately, little aided by the fact that his duties made him fabulously wealthy and the most powerful man in the country, give or take a king.

Said monarch was vigorous in that age-old pastime of the feudal monarchy, centralization of the power scattered among the nobility, further to which end he was happy to promote a competent administrator of scanty lineage and dependable loyalty.

Aggrieved lords, like the grasping Charles de Valois, were ready with their grudges against the unpopular minister when Philip shuffled off in November 1314. When charges of financial impropriety didn’t stick, they cooked up an allegation of sorcery — just then coming into vogue as a trump card in the game of judicial homicide.

Enguerrand hung two years upon the monumentally terrifying Montfaucon Gibbet (the link is to the structure’s French Wikipedia page), but everyone felt just terrible about it later. (the link is French, again) An actual inquiry — they skipped that step when they strung him up — exonerated the luckless minister, allowing his heirs to retrieve his body and a chunk of his fortune from the sympathetic king; Charles was so pursued by guilt that on his deathbed, he sent out a fat dispensation of alms with the request that recipients pray for both Enguerrand de Marigny and himself.

It worked … at least for Marigny’s reputation.

None can tell, after this lapse of time, whether this remorse proceeded from weakness of mind or sincerity of heart, and which of the two personages was really guilty; but, ages afterwards, such is the effect of blind, popular clamor and unrighteous judicial proceedings, that the condemned lives in history as a victim and all but a guileless being.

It was no hard feelings from Enguerrand’s little brother, Jean. The family influence had landed him a bishopric, and he held the job until his death in 1350, even repelling an English siege of Beauvais during the Hundred Years’ War.

Enguerrand de Marigny comes in for a passing notice as T.H. White affectionately surveys the Middle Ages in The Once and Future King:

What an amazing time the age of chivalry was! Everybody was essentially himself — was riotously busy fulfilling the vagaries of human nature … [a] coruscating mixture of oddities who reckoned that they possessed the things called souls as well as bodies, and who fulfilled them in the most surprising ways.

…

[Y]ou might have seen Enguerrand de Marigny, who built the enormous gallows at Mountfalcon, [sic] himself rotting and clanking on the same gallows, because he had been found guilty of Black Magic.*

Montfauçon was, as Sauval says, “the most ancient and the most superb gibbet in the kingdom.” …

Let the reader picture to himself, crowning a limestone hillock, an oblong mass of masonry fifteen feet in height, thirty wide, forty long, with a gate, an external railing and a platform; on this platform sixteen enormous pillars of rough hewn stone, thirty feet in height, arranged in a colonnade round three of the four sides of the mass which support them, bound together at their summits by heavy beams, whence hung chains at intervals; on all these chains, skeletons; in the vicinity, on the plain, a stone cross and two gibbets of secondary importance, which seemed to have sprung up as shoots around the central gallows; above all this, in the sky, a perpetual flock of crows; that was Montfauçon.

At the end of the fifteenth century, the formidable gibbet which dated from 1328, was already very much dilapidated; the beams were wormeaten, the chains rusted, the pillars green with mould; the layers of hewn stone were all cracked at their joints, and grass was growing on that platform which no feet touched. The monument made a horrible profile against the sky; especially at night when there was a little moonlight on those white skulls, or when the breeze of evening brushed the chains and the skeletons, and swayed all these in the darkness. The presence of this gibbet sufficed to render gloomy all the surrounding places.

The mass of masonry which served as foundation to the odious edifice was hollow. A huge cellar had been constructed there, closed by an old iron grating, which was out of order, into which were cast not only the human remains, which were taken from the chains of Montfauçon, but also the bodies of all the unfortunates executed on the other permanent gibbets of Paris. To that deep charnel-house, where so many human remains and so many crimes have rotted in company, many great ones of this world, many innocent people, have contributed their bones, from Enguerrand de Marigni, the first victim, and a just man, to Admiral de Coligni, who was its last, and who was also a just man.

Hugo — who, let us admit, is not to be depended upon for history — has elevated Marigny to the very first victim of the Montfaucon gallows, but the reader will also notice that the same passage dates the edifice’s construction thirteen years after Marigny’s own execution.

About this point, this blog runs against the limits of its writer’s access to primary documentation and werewithal to pursue it. Sources seem mightily confused on the embryonic era of Montfaucon; at least two other ministers — Pierre de La Brosse, a confidante of the previous king, and Pierre Remy, another royal treasurer hanged a generation after Marigny — also have their own claim to have been hanged on the structure they erected.

It may be that this was actually true of Remy, a less dramatically captivating figure with an official portfolio similar to Marigny’s, and the two simply became conflated in legend. Something certainly seems to have been built during his time, and it may have been the stone replacement for the original gallows.

The suggestion of someone who researched it more thoroughly than I have (another French page, but worth the visit if only for the pictorial schematics) is that the landmark structure may have predated all these men.** Brosse and Marigny, in this conception, may simply have worked various repairs upon it that became magnified in the retelling, while the gallows Remy set up might have been those on the secondary location, erected as a stopgap during a more thorough reconstruction of the permanent site, and/or reserved for more vulgar elements than ministers of the crown.

** We find repeated claims that the alleged “sorceror” Marigny engaged for his capital crime was hanged below him, which would support that notion; I have been unable to identify the provenance of this detail, however.
